Jesse Seldess (jseldess) commented:

PR: cockroachdb/cockroach#58670

From release notes:

A limited scan now checks for conflicting locks in an optimistic manner, which means it will not conflict with locks (typically unreplicated locks) that were held in the scan's full spans, but were not in the spans that were scanned until the limit was reached. This behavior can be turned off by changing the value of the [cluster setting](../v21.2/cluster-settings.html] kv.concurrency.optimistic_eval_limited_scans.enabled to false. [#58670][#58670)

Jira Issue: DOC-1332
